J. E. MUHLFELD LOCOMOTIVE TENDER Filed June 2l, 1929A l,753,2 l l INVENTOR Patented Apr. 8, 1930 UNITED @STATES JOHN E. Munn-FELD, or scAasnALE, NEwh-Yoax LocoMo'rIvE TENDER Application i'led January j21, v1929. {Serial No. 372,560.

This invention relates to locomotive tenders, and has for its primary object-and purpose `to provide'a tender particularly de-V signed for use i'nconne'ction with freight lo:

comotives having provision vfor the comfortable housing and protection ofthe conductor' or brakeman and means whereby easy and quick'communication may be had when l'necessary,'with the engineer.

More particularly, my. present invention contemplates the provisionbn'a rear eXtension ofthe tender 'under frame of a more or less commodious cabin in which the conductor or brakeman may be stationed and provided l'with 'a telephone or speaking tube connection with the engineer?s `cabin so that when itis necessary for the engineer and conductor to consult veach other, the conductor need not enter the englneers cabin, and is also protected against possible serious in] ury in the 'event ofy derailme'nt ofthe locomotive, boiler explosion, Orp-'otherv accident. :y y

Itisa further general object ofthe invention to prov-ide an `1mprfoved locomotive tendy er as 'ab'ove characterized which does not necessitate vmaterial;alter-ation 'in thepresent standard construction, or necessitate fa Idecrease inthe Water and coal, oil ory other fuel carrying capacity of the locomotive tender.

With the above and other objects'in view, the invention consists in the improved locomotive tender, and in the form, construction and relative arrangement of its several parts, as will be hereinafter more fully described, illustrated in 'the' accompanying drawings,

and subsequently incorporated in the subjoined claims. f Y

Y In the drawings, wherein I have lshown one simple and satisfactory embodiment of the Ll0 invention, and in which similar reference characters designate corresponding parts throughout the several views, Y

Figure 1 is a side elevation of a locomotive tender provided with my present improve- 35 ments;

Fig. 2 is a top plan view thereof, and Fig. 3 is an end elevation. In modern railway transportation systems, large high-powered freight locomotives are used for hauling freight trains which are trance door 11 and above ment 5, the cabin v.is of reduced width, or is 90p composed of from .100 `to 150 individual cars and measuring iin total length from 14500 'to 5700 feet. L

It has heretofore operation ductor and head brakeman to Ibe stationed in the Caboose at the rea-r end fof the train. When the train arrives at .points where train orders are received, it 'becomes necessary for the conductor and Vengineer to directly communicate with each other and "the former :must therefore, walk theentire length ofthe trainl fromvthecabovo'se Vto 'the engine cab'. This lconsumes a great deal of time with consequent delay 'in the lmovement lof the train. 65 Also, many other Ycases arise whereV the `conductor must leave the lCaboose `'and communi? cate with the engineer or to pick up or set out freight cars, and for other reasons.

It is the primary purpose of my present improvements to provide an engine tender construction which will eliminate delays incidentto the above cause and at the same time obvi-ate the necessity of the conductory entering the engineers'cabinon the locomotive. To this end, kas shown in the drawings, the conventional type of tender which I have selected for purposes yof illustration, is provided with a water carrying compartment indicated at 5, a compartment 6 for c oal, lignite 80 or other solid c'arbonaceous fuel, and a compartment 7 for fuel'oil. The 'under frame 8 of the Vtender is extended rearwardly beyond the' water vcompartment 5 as'shown at 9, and upon this frame,a cabin or 'auxiliary caboose '10 is con-y structed. As herein shown, this eabin is provided inv one side wall thereof with an enbeen customary in the` set back at this side ofthe tender as indicated at 12 so that the trainmen may ascenda-lad der indicated at A land walk over thetop of the tender when itis necessary cate with the engine crew. f' Within the cabin 12, a speaking ltube or telephone connection indicated-at 13 is installed whichy affordsready communication between the occupant of the jcabin and-the engineer.

of such freight trains for the con- 55 rear 'extensionof the tender underl 85v the water compartf to communi'- Additional facilities are also pro- 1 Y for the conductor,

Y may be received.

Vvided within the cabin for the purpose of making out reports and other clerical work which may be required of the conductor enroute. Y

From the above, it will be seen that by providing the cabin at the rear end of the tender he may at all times get into instant. communication with the Vlocomotive engineer for the purpose of consultation as to train stops for the purpose of taking on Water, and to consider such train'orders vas It is of course, understood that the rear end of the train will be protected by a brakeman or fiagman who remains at all times in the oabooseat the rear end of the Y train. By locatingthe'l-ocomotiveengineer and Aconductor close together, it; will vbe apparent that delays in the train movementfincident tothe necessity ofthe conductor walkingl fromthe Caboose at the rear endl of the train to theengineeris cabin and then return ling-to the caboose, are entirely eliminated, so that by means of my improvements, the transportation of freight may be Vmaterially eX- pedited. t A further advantage resides in the fact that sincethe conductor need not at any timeenter Vthe cabin of the locomotive, in the event of a boiler explosion orother accident such as a broken draw bar, side rod or crank pin, a broken ,or loosedriving wheel tire or derailment of the locomotive, liability of the conductor, head brakeman, or other persons being killed `or `seriously injured', is greatly reduced.

' .f kFrom the foregoing descriptionconsidered in connection with the accompanying drawing, t-he nature of my present invention and its several advantages in practicaluse will be readily understood. `While I have shown aparticular type of locomotive tender and a desirable form and i construction of the cabin which is erected on the rear extension ofthe tender under frame, it is to be understood that the invention is applicable'to variousother standard forms of tenders and that the auxiliary cabin or caboose may also beconsiderably modied in the details of its construction. By the kprovision of such a separate compartment for the Vhead brakeman and conductor of the'train, the engineer 1s never disturbed by the'presence of members of the train crew in his cabin, and possibility of erroneous'interpretation of 'signals gii-ien'either` by the hand or. by a lantern, is greatly reduced. It will further be apparent that-the incorporation of my-present improvements will not materially add to the manufacturing cost of such locomotive tendi While Iihave herein disclosed a practical embodiment. of 'the invention, it is neverthej less tobe understood" that thev same might be incorporated Ain various other `structural Y changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

I claim:

l. A tender for locomotives comprising an extended under frame, a tender body supported upon said extended under frame, and a cabin at the rear end of the tender body affording a compartment for housing members of the train crew.

` 2. A locomotive tender comprising an under frame, a tender body supported on the under frame, said under frame having a rear end extension projecting beyond the tender body, and a cabin supported on said under frame extension providing a compartment for housing members ofthe train crew.

3. A locomotive tender comprising an under frame, a tender body supported on the under frame, said under frame having tender body,a cabin supported on said under frame extension providing a compartmentV for housing members of the train crew, and means between the ytender cabin and the engine cab affording verbal communication between the occupant thereof and the engine crew. Y Y

l. A locomotive tender comprising an under frame, a tender body supported on the under frame, said under frame having a rear end extension projecting beyond the tender body, a cabin supported Yon said under frame extension providing a compartment for housingmembers of the train crew, and a telephone or speaking tube installed in the cabin connected with the engineers cabin,

5. A locomotive tender comprising an under frame, a. tender body supported on said under frame having water and fuel compartments, said under frame having a rear end extension projecting `beyond Vthe tender body, acabin supported on said under frame extension providing a compartment for members of the train crew, said compartment projecting vertically above the tender body and being cut away at one side thereof to provide a walk, a ladder mounted on the rear side of the cabin leading to said walk, and a telephone or speaking tube installed in said compartment and connected with the engineers cabin. u
